IBKPROVEMENT IN BUTTONS.

The Schedule referred to in these'Letters Patent and maLn'ng part of the same.

tion.

Figure 2 isa similar section ota modification thereof. Similar' letters indicate corresponding parts. This invention relates to an improvement upon the inventiouof A. K.' Browne, for a collar-button, for which Letters Patent were granted, September 25,

1866, said invention consisting of a button, the back and the head 0f which are united by a spring-catch, which is attached to the head, and which, when said head is inserted into the shank, catches under a stop, or shoulder in the interior ofthe shank, from which it can be released by the pressure of the Enger on a button inserted into the inner end ofthe shank, and provided with an` inclined plane, in such a manner that the shank of the button-back can be readily passed through the holes of the shirt-band and collar, and the head can be easily attached and detached without injuring or spoiling the appearance of the collar.

My improvement consists in securing to the head and the back of the button, tubular shanks, which iit into each other. One of these tubes contains the spring-catches, and the other' contains the ring, which operates with the catches, to hold. the head and hack in position, and also the button, which causes the disengagement of said head and back.

'lhe tubes enclose the spring-catches and ring, and present the appearance of a solid shank, with which the cloth will be in contact when the button is applied to4 the garment. l

A represents my collar-button, which is composed of the head a and back b.

l` rom the head extends a tubular shank, c, which tits into the tubular shank d of the back.

To the interior of the tube c are secured one or more catches, e, (two being shown in the drawing,) and if said tube is forced down into the shank d, these catches Figure l represents a central section of this invenslide over and finally catch under the ring j, which is secured in the interior of the shank d, and thereby the two parts are firmly locked together. l

Through the inner end of the shank d is introduced a button, g, which is provided with a central conical depression, forming inclined planes, 7i., and if said, button is crowded in, these inclined planes act on" the spiing-catches, and compress the same, so that they release the ring f, and the head c can be withdrawn.

When the head is reinserted, the button y is forced` back to its original position.

To prevent said button fromdropping out of the shank, it is provided with a shoulder, rL, which catches' up against an internal flange, or lip, j, as shown in fig. l; or, instead of this lip, or ange, a pin, il, may be employed, which works in suitable grooves', ji, in the shank, `as shown in tig. 2.

By these means, a collar-button is obtained which can'be readily inserted Without straining the button holes `of the shirt-band, or collar, and Without spoiling the smoothness ofthe latter; and furthermore, a slight pressure on the button g is sufficient to disengage the head, so that the button can be removed without trouble. ,y

The head of the button is rounded, and projects but very little beyond the back plate ofthe button, so that it cannot possibly incommode the wearer; and not withstanding this fact, it is so situated that it can be readily reached and operated.

By placing the ring, or .shoulder f into the interior of the' shank, the locking-devices are entirely concealed when the button is in use, and they are not liable to catch in the shirt. Y

Having thus described my invention,

What I claim as new, and desire to secure by Letters Patent, is-` AThe tubular shanks c d,iitting within each other,

one of which is secured tothe head c, and receives the.

spring-catches e, and the other is secured to the back, b, and contains the ring f and button g, constructed and operating substantially as and for the purpose described.
